Quality assurance for Heat Treated products
Caution
- The hardened depth and distribution of heat treated areas may vary depending on the thickness and shape of the material.
- When parts are heat treated, the outer surface tends to be harder, while the inner areas tend to remain softer. During inspection the hardening will be confirmed to be uniform on average.
- Media blasting may be performed to remove surface contamination after quenching. There will be no change in accuracy after the treatment. Blast type cannot be specified.
- Grinding may be performed during the finishing process.
- Grinding cannot be specified. The factory will determine if grinding is necessary to guarantee dimensional accuracy.
- Hardness measurement marks may remain in areas. To confirm the inspection points in advance, please add information in the comments and request a manual quote.
